Two button mac mouse (Score 1)

It seems that everyone is thinking that apple is going to produce a standard two button mouse. I for one will be disappointed if that were the case, apple say they pride themselves on hiring people who think outside the box. I have read that there are some problems with the new trackpad on the current line of powerbooks but I would still like to try it, scrolling by using two fingers instead of one sounds like it could work better than using the sides of the tackpad like I'm currently doing. I would be intrested in trying a mouse where the second button acted as a toggle that converted mouse motion into scrolling. While the second button was down, the main button could also be used as a second mouse button or whatever someone thought would be a better function. Maybe I have used linux too much but I find it usefull to have a middle mouse button so I can highlight something and click a button so it is copied to somewhere else. I can get by without it, using cmd c and cmd v, or ctrl c and ctrl v depending on the computer, but I feel having it on the mouse is faster.
